Amazing Magnetic Levitation Device

CLM 2 magnetic levitation module provided by Crealev. This device is to huge and powerful, it’s really hard to believe.

This unit can float objects weighing near 20 pounds. Even though it’s beautiful to walk in the room and see this unit sitting there. The magnetic disc is hidden under the chessboard, for instance. The visual of a floating pillow supporting a 7 pound brick is fun to see. And then the last was just so cool to see.

Are You Alone? (Infographic)

Are you alone? To answer this question we have to take a look what “you” are first. What are you made of and where you stand in this universe. Are you your body? Your atoms? And how are your parts connected to the big picture?

Misconceptions About the Universe

Can we see things travelling faster than light?

The expanding universe is a complicated place. During inflation the universe expanded faster than light, but that’s something that actually happens all the time, it’s happening right now. This doesn’t violate Einstein’s theory of relativity since nothing is moving through space faster than light, it’s just that space itself is expanding such that far away objects are receding rapidly from each other.

Common sense would dictate that objects moving away from us faster than light should be invisible, but they aren’t. This is because light can travel from regions of space which are superluminal relative to us into regions that are subluminal. So our observable universe is bigger than our Hubble sphere – it’s limited by the particle horizon, the distance light could travel to us since the beginning of time as we know it.
